Description
Technical field
The present invention relates to a kind of prefabricated shear wall and overlapping plate node.
Background technology
Prefabricated assembling type reinforced concrete structure the developed countries such as America and Europe, Japan had more practical application and
More ripe technical research.In recent years, national development green building, greatly develops assembled architecture, promotes construction industry transition
Upgrading.With the quickening of China " building industrialization, housing industrialization " process, the application of prefabricated assembled shear wall structure is increasingly
Extensively, the country deepens continuously to the practical application of prefabrication and theoretical research.
But, the country is still within the starting stage of research application in the field, lacks related specifications and research to the skill
The guidance of art is supported.Meanwhile, it is the construction experience of domestic prefabricated assembling type reinforced concrete structure at this stage, construction technology, pre-
All there is larger deficiency in the optimization design of component processed.
When existing cast-in-place concrete structure is constructed at the scene, the arrangement colligation process of reinforcing bar is numerous and diverse, workload is big, work effect
Rate is low.And the work progress of shear wall and overlapping plate node is in prefabricated assembling type reinforced concrete structure at present：Grout sleeve
The bottom of precast shear wall is embedded in, the top vertical reinforcement of precast shear wall is overhanging, then by the prefabricated shearing of last layer
The bottom grout sleeve of wall is enclosed on the vertical protruding bar in the top of this layer of precast shear wall and is in the milk, so that cutting levels
Power wall is connected.In this way, there is problems with：The plastic hinge of general shear wall is formed at the bottom of shear wall, but by
In the effect of grout sleeve so that the bottom of shear wall does not become plastic hinge, so cause at grout sleeve lower end position
This layer of top rebars are broken, so as to occur brittle break.
Existing assembled steel reinforced concrete shear force wall and superimposed sheet structural system also exist efficiency of construction it is not high, install essence
The problem of spending excessively cumbersome poor, live assembling reinforcement, many live supported amounts, globality and poor seismic behavior.These problems are all
Directly constrain building industrialization environmental protection, economy, efficient, the performance of the advantage such as high-quality.
The content of the invention
There is preferable overall performance and the high assembled of anti-seismic performance, efficiency of construction it is an object of the invention to provide a kind of
Precast shear wall and overlapping plate node, can overcome existing assembled steel reinforced concrete shear force wall and superimposed sheet structural system to construct
Inefficient, installation accuracy is poor, live assembling reinforcement excessively cumbersome shortcoming, reduces live supported amount, improves assembled steel
The globality and anti-seismic performance of reinforced concrete shear wall and overlapping plate node, are suitable for the wide popularization and application in building structure.
The purpose of the present invention is realized by following technical measures：A kind of prefabricated shear wall and superimposed sheet section
Point, including precast shear wall and superimposed sheet, it is characterised in that：The superimposed sheet it is main by prefabricated board, reinforced mesh and after pour mixed
Solidifying soil overlapping layers composition, the reinforced mesh level is described located at the top of prefabricated board and in rear pouring concrete overlapping layers
Reinforced mesh is together with reinforcing bar colligation corresponding in precast shear wall, superimposed sheet.In precast shear wall and the section of superimposed sheet
Vertical grout sleeve is provided with point, the bottom of the grout sleeve is embedded in the upper end of precast shear wall, and remainder is then
In the rear pouring concrete overlapping layers of superimposed sheet, and the bottom of grout sleeve is enclosed on the vertical reinforcement in precast shear wall
On top, the precast shear wall positioned at a upper floor overhangs downwards vertical reinforcement, and the vertical reinforcement is from the top of grout sleeve
Insert in it, the discharge pipe and grout pipe connected with inside it is respectively equipped with the upper and lower part of grout sleeve, by from filling
Slurry pipe pours into grouting material into grout sleeve, until being overflowed from discharge pipe so as to irrigate full irrigation slurry in grout sleeve.
Grout sleeve of the present invention is the connector of the upper and lower shear wall, positioned at the top of precast shear wall, and is embedded in
In precast shear wall upper end and rear pouring concrete overlapping layers, so shear wall can form plastic hinge in bottom, it is to avoid existing node
Situation about bottom reinforcement bars can be broken.Moreover, the present invention solves prefabricated concrete structure when constructing at the scene, the cloth of reinforcing bar
The problem of putting colligation tedious process, the present invention can fast and flexible at the scene setting additional bar, be easy to the prefabricated building of assembling overlap joint
Plate, when the present invention can solve cast-in-place concrete structure and construct at the scene, the arrangement colligation process of reinforcing bar is numerous and diverse, workload, work
The problem of inefficiency, the present invention only need to be in the case where meeting Seismic Design Requirements in the corresponding reinforcing bar of Facility Layout colligation, and designs
The suspension centre of lifting, greatly reduces site layout project reinforcing work amount, reduces difficulty of construction, while improving reinforcing bar colligation
Precision, be conducive to standardized production and the installation of prefabricated components.Precast shear wall, the prefabricated board of superimposed sheet are covered by being in the milk
Wall and superimposed sheet above and below interconnection and bonding interlocking formation shear wall between cylinder, reinforced mesh and rear pouring concrete
Between node, so as to improve the globality and shock resistance of the node.
